Title: Nozzle blade assembly for turbines
IPC: F01D9/04
Filed: 1965-09-14
Abstract: 1,048,340. Turbines. WORTHINGTON CORPORATION. Sept. 14, 1965 [Nov. 5, 1964], No. 39117/65. Heading F1T. A nozzle blade assembly preferably in two halves and suitable for use in a radial inlet, double flow gas turbine having first stage rotor blades 22, an outer sheet metal casing (not shown) and an inner casing 10 provided with a lining 14 positioned and sealed at 16, comprises independently removable blades 40 each consisting of an aerofoil member 42 anda member 44 for covering a preferably non- circular longitudinal groove 46, Fig. 3 (not shown), therein. The members 42, 44 may be of stainless steel. After assembly of the member 42 by its groove on to a support bolt 32, the cover member 44 is connected to the member 42 by screws 50 which thereafter are preferably welded over and ground flush with the blade surface. On initial assembly each blade 40 is adjusted by square end 74 of bolt 32 to the angular position for optimum turbine efficiency and locked therein by nuts 38. A hole 64 is then drilled and tapped in the casing 10 through one of a number of angularly spaced bores 62 in enlarged portion 34 of belt 32, and a screw 66 inserted therein to positively secure the blade against angular movement. A nut 70 locked by peening at 76 prevents disengagement of screw 66. The angular position of the blade may later be adjusted by engaging the screw 66 with the tapped hole 64 through a different bore 62. To facilitate determination of the blade angular position for turbine optimum efficiency, the inflow passage to one side of the turbine is covered by a blank 86, Fig. 4 (not shown), located over bolts 32 and secured to the casing 10 by plates (100) and bolts (102, 104), and the flow and length of the nozzle blades are reduced by one half. After the blade angular position has been established, the blank and half-length blades are replaced by the full-length blades 40.

Filed: 1929-12-23
Abstract: 351,908. Master control of motors ; controllers. SULLIVAN MACHINERY CO.; 400, North Michigan Avenue, Chicago, U.S.A. Dec. 23, 1929, No. 39301. Convention date, Jan. 2. Void [Published under Sect. 91 of the Acts]. [Class 38 (iii).] With auxiliary switches; locking electromagnetically.-A pilot switch for a contactor starting system for a motor, and a motor reversing switch are combined in a single unit in such a way that although the former may be operated at will, the latter cannot be opened until the motor is substantially at rest. An operating shaft 9, Fig. 2, is connected by gearing to a toothed movable element 15, upon which are mounted contacts 18, 19 which slide over stationary contacts 54, 55, 58, 59, Fig. 4. A number of the teeth 30 on the periphery of the member 15 are reduced in length to form a recess 53 on which the arm 49 of the pilot switch rests, closure of this switch being effected by rotating element 15 to bring full length teeth into connection with the switch arm 49. When the pilot switch is closed by placing the reverse switch in one or other of its extreme positions the first contactor 68, Fig. 7, is closed and also a switch 72. This closes the next contactor 69 and short circuits the first section of the starting resistance 77. Similarly contactors 70, 71 are closed in turn and the motor is placed directly across the supply. With the reverse switch in one of its extreme positions a coil 40 connected across the motor armature is energized and a plunger 39, Fig. 2, rests in one of two recesses 37, 38 in the member 15. Owing to the length of these recesses, the reverse switch can be moved the small amount necessary to open the pilot switch, but it cannot be moved to open its own contacts, until the motor comes to rest. The operating shaft 9 is moved by a handle so attached to it that the reversing switch cannot be rotated beyond the central position without pausing to slide the handle along the shaft. Specification 243,964, [Class 79 (v), Motor vehicles, Steering &c.], is referred to.

Title: Improvements in or relating to the control of illuminants
Inventor: CALKIN ROBERT BERNARD
IPC: G01J3/46
Filed: 1960-11-16
Abstract: 1, 010, 551. Colour photography; filters. KODAK Ltd. Nov. 16, 1961 [Nov. 16, 1960], No. 39439/60. Headings G2C and G2J. In Specification 969,003 a method of controlling illuminants for use in colour measurement or reproduction is described in which an upper row of filters consisting of magenta, absorbing green, a cyan filter absorbing red with an orange correcting filter between them absorbing the same amount of blue as the magenta and cyan filters is placed adjustably into a beam of light containing colours in the blue, green and red regions of the spectrum, and below it a lower row of filters consisting of a yellow filter absorbing blue, a blue filter absorbing green and red with an orange correcting filter between them having the same green to red transmission ratio as the blue filter and the same green and red transmissions as the yellow filter is also adjustably inserted into the beam. With such an arrangement, movement of the lower row of filters affects only the ratio of blue light to green and red light but the movement of the upper row of filters not only affects the ratio of green to red light but also varies the ratio of the red and green light to the blue light. Thus the setting of the lower row is dependent upon that of the upper row and according to the present device a filter row comprises at least two filters one of which has a low transmission in one region of the spectrum e.g. green and higher transmission in the other two regions, the second filter which is adjacent to or spaced therefrom has a low transmission in a second region of the spectrum e.g. red and higher transmission in the other two regions, the transmissions of the filters in the third region of the spectrum e.g. blue being such that in the light passed by the filters the ratio of the intensity of the third region e.g. blue to the combined intensities of the other two regions remains constant for all positions of the filter row. A compensating filter may also be placed between the two filters in the row. In an example one row consisted of Cyan + Pale Yellow; Pink; Magenta + Pale Yellow. The pale yellow filters were such that with the inherent blue absorptions of the cyan and magenta filters a density of 0.3 was obtained respectively in each case. The pink compensating filter had the same green absorption as the cyan + pale yellow filter and the same red absorption as the magenta + pale yellow filter. The second row of filters consisted of Yellow; Pink; Blue. The pink compensating filter had the same red and green transmissions as the yellow filter and the same ratio of transmissions as the blue filter. Specifications 660,099 and 941,574 are referred to.

Abstract: 1,152,594. Producing articles from resinimpregnated threads. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. 5 Sept., 1966 [6 Sept., 1965], No. 39534/66. Heading B8G. Threads impregnated with a thermosetting resin are wound on to a core (not shown) mounted on a shaft 39 rotating about its axis a-a as well as an axis b-b passing through the axis a-a, the inclination of the two axes being varied by adjusting the axis a-a so that the centre of gravity Z of the core is only displaced in a direction parallel to the axis b-b. In Fig. 1, variation of the inclination of the axis a-a causes the centre of gravity Z of the body being wound to move along the axis b-b. The table 20 rotates about the axis b-b. Mounted on table 20 is a slide 42 on which is pivotally mounted the shaft 39. A motor 52 drives a screw shaft 46 to cause the slide 42 to be displaced radially across the table 20. Thin radial movement of the slide 42 causes a guide wheel 51 to move along a fixed slot 49 in a manner varying the inclination of the axis a-a, Fig. 2 (not shown) is similar to Fig. 1 except that the member 42 is fixed in position on the table 20. When the axis a-a has its inclination varied, piston and cylinder arrangements are used to cause axial movement of the axis a-a in a manner maintaining the centre of gravity Z on the axis b-b of the table 20.

Title: Improvements in the production of vitamin a and vitamin a esters
Filed: 1957-12-20
Abstract: Vitamin A or esters thereof are produced by oxidizing axerophten, if desired in the presence of acylating agents, with selenium dioxide, preferably in the presence of a mercuric salt and in the absence of air.  When it is desired to oxidize and acylate in one step, the acylating agent (e.g. anhydrides of aliphatic, cyclo-aliphatic or aromatic acids) can serve as solvent.  Other suitable solvents mentioned are alcohols (e.g. ethanol), ethers (e.g. dioxane), hydrocarbons (e.g. benzene or cyclohexane), nitrobenzene, acetonitrile or glacial acetic acid. Mercuric salts which may be used are the chloride, sulphate and acetate.  The products may be isolated from the reaction mixture by, for example, distribution between different kinds of solvents (e.g. petroleum ether and aqueous methanol), or/and by chromatography and fractional distillation.  In the examples, Vitamin A and its acetate and anhydro-Vitamin A are made. Specification 778,487 is referred to.

Title: Organopolysiloxane compositions
Filed: 1958-12-10
Abstract: A composition which can be vulcanised at room temperature is made by malaxating 100 parts (by weight) of a liquid linear diorganopolysiloxane, having a viscosity between 5,000 and 500,000 cs. at 25 DEG C. and containing at least 0,1% by weight of Si-bonded OH groups, 5 to 50 parts of a finely divided filler other than ZnO, and 10 to 50 parts of ZnO, and heating the mixture at 50 DEG  to 200 DEG  C.  The siloxane may contain Si-bonded alkyl, alkenyl, aryl or aralkyl radicals.  The mixture may be heated either in an open vessel to permit escape of volatiles or in a closed vessel.  Conventicnal fillers are specified, though combustion silica should preferably constitute at least part of the filling material.  An organic amino compound serving as a vulcanisation catalyst, e.g. diethylaminoalcohol, ethylhydroxypiperidine or an ethanol amine may also be added before the malaxation, or before the heat treatment or afterwards to the cold mixture.  In Examples (1) a dimethylsiloxane oil containing 0,15% by weight of Si-OH groups was made by heating at 150 DEG C. in nitrogen octamethylcyclotetrasiloxane and aqueous KOH. Water was added slowly in fractions to the resulting hot oil, and after cooling, the KOH was neutralised by adding silica to yield a liquid from which volatiles were removed by heating in a current of nitrogen.  The resulting liquid was then mixed with combustion silica, diatomaceous earth, ZnO and iron oxide ; after cold malaxation for 1 1/2 hours a further quantity of the siloxane was added and the mixture heated for 2 hours at 135 DEG  C. After cooling, diethylaminoalcohol was incorporated to give a paste which was converted into an elastic solid in 2 1/2 minutes after incorporation of methyltriacetoxysilane ; (2) a methylphenylsiloxane oil prepared and malaxated as in (1) gave a paste which set to an elastic solid in 3 minutes after mixing with methyltriacetoxy silane. After storing for 15 months, the setting times of the pastes were unaltered.  Uses : for taking dental impressions.  Specification 803,262 is referred to.
